摘要：
The multiferroic material BaMnF4 has been investigated with unpolarized and polarized neutron diffraction. The structure has been shown to be antiferromagnetic. The magnetic moments are aligned at 12 degrees to the b direction in the bc plane, 3 degrees different from the previously determined value. The ferromagnetic component that is indicative of the linear magnetoelectric effect was not observed.
